Desktop Toy V8

The videos of it on the desk don't show much because it's pretty loud, and the office was busy at the time of the video. Also, the video where it wouldn't turn over at low speeds was because I had a piston arm rubbing wrong. I fixed that and everything ran smoothly again. Here are the parts I used. It's powered by a USB cable. Instructions: Print the files from the original V8 model, then print these pieces. The Engine Base and PWM base have pieces that slot together to hold them (easier than printing one large piece). They will hold the V8 assembly and the electric motor assembly. Then print the PWM bot and top to hold the board. I printed it with a channel for my cabling. I used hot glue to attach the board to print but m3 bolts should work, I believe... I forgot what I made the tolerances for because I went with hot glue instead. Drill a hole into the PWM top piece for the wiring of the motor to come down. I hot glued the motor cap to the PWM top so that I could have some rigidity but still take it apart later. I also hot glued the PWM base to PWM bot so that it didn't move around during movement. Print knob for PWM board and use connector to attach to motor, find an appropriate drillbit that will turn your motor.
